4 Claims.

This invention relates to an improved water heater for oil burners, and more particularly, for range oil burners, that is, oil burners of the blue iiame type designed to be installed in the iire boxes of ordinary coal-burning ranges and the like to provide the necessary heat in place of coal and wood.

One object ci this invention is' to provide a water heater adapted to t substantially all range oil burners made by the various manufacturers.

Another object of this invention is to provide a compact water heater which can be readily installed for use. Y

Another object of this invention is to provide a Water heater of Very efrlicient, simple construction.

With the above and other objects in view, this invention includes the improved features, parts and combinations of partsY disclosed in the following description, appended claims and accompanying drawing forming a part of this speciiication.

In the accompanying drawing:

Fig. 1 is a perspective View illustrating my invention shown in position between two oilV burners;

Fig. 2 is a perspective view of the water heater,

detached; Y

Fig. 3 is a sectional view on the line Fig. 1; and

Fig. 4 is a sectional View on the line 4-4 of Fig. 2.

In carrying out my invention, I form a waterh'eating shell or casing 10 of any suitable material and having inwardly-curved sides'll and 12, which adapts the device to be located between burners 13 and 14 of the usual blue ame type which include perforated cylinders which surround the burners.

For convenience, the casing 10 is provided with a socket 15 on its bottom wall 16, to set over the upper end of a post 17 which is commonly employed to support a shelf 18 on which the burners 13 and 14 are mounted. One end of' the casing 10 is provided with a lower inletopening 19 and an upper outlet-opening 20, the opening 19 being adapted to be connected with an inlet-pipe 21 and the opening 20 with an outlet-pipe 22 leading to a supply tank or to any desired outlet.

Within the casing 10 above the inlet 19 is a longitudinal baie 23, and extending transversely through both sides 24 and 25 of the casing are a series of horizontal passages 26 which are intersected by vertical passages 27 extending through the top 28 of the casing.

The two concave or inwardly-curved side walls of the casing, being located adjacent the burners, receive heat therefrom with great efficiency since about 65% of the casing wall surface is immediately adjacent the burners, so that water in the casing is rapidly heated. Also, by providing the intersecting passages 26 and 27, heat is carried into the center ofthe casing and upward through the top thereof, so that water in the interior part of the casing is rapidly heated by virtue oi the fact that the passages 26 and 27 act as chimneys or ilues to conduct heated gases inwardly in opposite directions through the passages 26 and thence upwardly through the passages 27, thus causing the walls 29 and 30k of the passages 26 and 27, respectively, to eiliciently extract heat from the heated gases.

The baiile 23 which extends longitudinally rearwardly and downwardly to a location 31 and forces the cold water to travel to a location 32 at the opposite or rear 'end of the casing from where it travels upwardly to a region 33, and thence forwardly through the channels 34, 35 and 36 and cross-channels 37, so as to continuously extract heat from the walls 29 and 30 of the passages 26 and 27.

This device is readily formed and may be readily installed in any range equipped with` blue flame burners, and by arranging the device between two burners, both sides are exposed to heat, thus efficiently receiving and conserving heat, which is not the case when coils or other means are employed to surround the burners as the outer surfacesof such coils tend to radiate heat instead of conserving it. Y

The invention may be carried out in other speciiic ways than that herein set forth without departing irom the spirit and essential characteristics of the invention, and the present embodiment is therefore to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein. I

I claim:

1. A water heater for oil burners comprising .a casing having inwardly-curving side walls adapted to be placed between two burners, said casing provided with inletand outlet-openings, and a downwardly-inclined baille-plate above the lower opening, said casing provided with a series of transverse openings above the said baille-plate. f

2. A water heater for oil burners comprising a casing having inwardly-curved side walls, inletand outlet-openings, and a series of transverse passages opening through the side walls of the casing, said transverse passages ntersected by vertical passages opening through the top of the casing.

3. A Water heater for oil burners comprising a` casing having inwardly-curving side Walls adapted to be placed between two burners, said casing provided with inletand out1et-openings,

and a downwardly-inclined bathe-plate above the lower opening, said casing provided with a transverse opening above the said bafe-plate.

4. A Water heater for oil burners comprising a easing having inwardly-curved side walls, inletand outlet-openings, and a transverse passage opening through the side Walls of the casing, said transverse passage intersected by a. vertical passage opening through the top of the casing.
